Title: Conductor paste
Inventor: KAWAKAMI KATSUYA
IPC: H05K1/09
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To provide a conductor paste that lessens the decrease of viscosity with time. SOLUTION: A powder of an ethyl cellulose A having a lower viscosity value is mixed into butyl Carbitol acetate (a solvent) and dissolved therein by heating to form an organic vehicle A. A powder of an ethyl cellulose B having a higher viscosity value is mixed into butyl Carbitol acetate and dissolved therein by heating to form an organic vehicle B. Then, the organic vehicle A and the organic vehicle B are mixed to form an organic vehicle A+B. The organic vehicle A+B is mixed with a conductor powder and sufficiently kneaded by three rolls in a kneader or the like, and is pasted to thereby form a conductor paste. The mixing ratio of the conductor powder to the organic vehicle A+B is preferably 60-90 wt.% conductor powder to 40-10 wt.% organic vehicle.  The thus-produced conductor paste achieves a small decrease of viscosity with time and assures continuously stabilized printability irrespective of the lapse of time, It is preferable that three or more ethyl celluloses having respective different viscosity values may be blended.

Abstract: PURPOSE:To obtain a floating state from the earth without using a DC/DC converter by using a reference power supply, an adder and two constant current circuits and adjusting voltage to be impressed to a conductor resistor by an output from the adder. CONSTITUTION:When the voltage of the reference power supply 3 is set up to 1V e.g., and the gain of an amplifier 1a and that of an amplifier 1c are respectively set up to '2' and '1', 1V voltage appears on both ends of a load resistor 1b. Similarly, 1V voltage appears on both ends of a load resistor 2b. The adder 4 adds the output voltage Vo of the power supply 3, (voltage on the end part 5a of the conductor resistor 5+DELTAVea) and (voltage on the end part 5b of the resistor 5-DELTAVea). When (voltage + DELTAVea) and (voltage - DELTAVea) are equal to each other, both values are offset each other and only the inversed voltage of the reference voltage Vo -Vo is applied to the input terminal of the amplifier 2a as the output of the adder 4. Consequently, the end part 5a of the resistor 5 is turned to +(1/2)Ve voltage and the other and 5b of the resistor 5 is turned to -(1/2)Ve voltage.
